Continuous soil-gas radon and thoron measurements were carried out at 15 days interval along Mat fault in Mizoram (India), which lies in the seismic zone V of the seismic zonation map of India. The study was carried out from March 2012 to February 2013 using LR-115 Type II detectors,...

In this paper, we report that the ratio of broadband energy (0.01–2 Hz) to high-frequency energy (0.3–2 Hz), E <Subscript>r</Subscript>, estimated from regional seismograms of India, might be a useful parameter in estimating tsunami potential of earthquakes in the Sumatra–Andaman region. E <Subscript>r</Subscript> is expected to be...</subscript></subscript>

Alaknanda river basin is considered to be tectonically active where damaging earthquakes and landslides have occurred. The whole basin was divided into 8 sub-basins to carry out morphometric analyses, hypsometric integral (HI) analysis and valley floor width to valley height ratio (V <Subscript>f</Subscript>) factor....</subscript>
